Earthworm Regeneration Myth: Cutting Worms Doesn't Create Two Worms

Earthworms don't survive bisection. Their nervous, digestive, and circulatory systems are severed. A small tail tip may regenerate; mid-body cuts are fatal.

Head vs. Tail Identification

The thick, light-colored clitellum (band) is closer to the head. Mouth and reproductive pores are between clitellum and head. Worms know their orientation instinctively.

Population Potential

Under ideal conditions, 10 lbs of worms can become 2+ tons in two years. But not through cutting—they reproduce the old-fashioned way.
